SKF's new competence in lubrication systems; optimized and integrated system solutions for higher performance and productivity

|With the acquisition of Willy Vogel AG in July 2004, SKF has now added a new core competence to its broad range of customer offerings. The new lubrication systems competence will be combined with other SKF competences from across its 5 Platforms to offer optimized and integrated system solutions that deliver higher performance and productivity.
Centralised lubrication systems; supply a few friction points or thousands of friction points with the right lubricant, in the right amount, at the right time, to the right point of use.
Many of the friction points are bearings. SKF's combined knowledge in bearings and bearing condition monitoring can now be coupled with centralised lubrication systems to allow optimal systems to be designed that increase performance, lower maintenance costs, save energy, reduce lubricant consumption, increase reliability and uptime of equipment.
In process plant applications an integrated bearing and lubrication monitoring system from SKF also makes life easier for operational personnel because they can get all necessary information from one system via an easy to use Human Machine Interface.
Lubrication systems are needed in many applications and industries, Some of these are;
* process plant; Pulp and paper processing, etc
* manufacturing; automotive presses, steel rolling mills etc
* printing machines; all types and sizes,
* wind turbines
* production; woodworking machines, large size presses, etc
* machine tools; all types of machinery, bed slides, etc
* on- and off-road vehicles; trucks, buses, excavators, tractors, etc
* mining machinery
* large diesel engines
Special integrated system solution; An example of special integration is machine tool spindles where SKF has a new range of high speed machine tool spindles with automatic lubrication, including special 'oil streak' sensors to monitor and ensure lubricant is always available when the spindle is in operation. Such a monitoring system prevents extremely costly spindle failures that could occur if the lubricant supply to the spindle bearings should stop; eg. through a broken supply line or a loss of compressed air
Customer benefits include a fully optimized spindle system with better machining performance, greater reliability of the spindle, much less lubricant consumption and higher productivity.
Special high-tech lubricating solutions
Minimal Quantity Lubrication for machining operations to reduce machining time, increase tool life, reduce the amount of lubricant used, improve productivity and reduce damaging effects to the operator and environment that can occur with oil mist.
In machining operations such as turning, milling, drilling, etc average machining times can be reduced by 40% and tool life can be extended by 300%. Lubricant use can be greatly reduced compared to water-based flood coolant systems.
In Minimal Quantity Lubrication systems an extremely small and controlled amount of lubricant is supplied to the cutting edge of the cutting tool in an aerosol mix of oil and air. The amount is so small that the cutting operation appears to be 'dry' and there is no oil mist or excess oil that needs removing for health, safety and environmental reasons.
Lubrication of cylinders in large 2-stroke diesel engines. A new development that gives higher operational reliability, 30% oil savings compared to previous systems, and is serviceable while the engine is in operation.
This results in more transport time because the maintenance would otherwise have to be done after first stopping the ship. And the oil savings are in excess of 100,000 Euro every year!
Wheel flange lubrication for rail vehicles. A system that sprays small amounts of lubricant onto the wheel flanges while the train is in motion. It is used on freight trains, trams, inner city trains and high speed passenger trains.
These systems result in considerable noise reduction, up to 15% less energy consumption, up to 80% less wear on the wheels and rails, and a reduced potential of derailment when travelling through curves in the track.
